Auto engines are engines that are integral components to the operation and running of an automobile. There are a few different types of engines, the most common being the internal combustion engine, which runs on fuels such as petrol, diesel, propane or natural gas. Other types of vehicles include hybrid vehicles, plug-in hybrids, fuel cell vehicles and electric cars. Each engine consists of differing opponents and run on different fuels, making each one increasingly complex in design as they are manufactured to run on the newer renewable energies and 'clean' systems.
